Due to the rounded corner setting of the end wall of the through hole 202, the wear of the pull rope 109 at the through hole 202 is reduced, and the service life of the pull rope 109 is improved. In addition, through the setting of the heat dissipation groove 205, the interior of the protective shell 201 is kept in circulation with the outside air, and the heat generated by the driving motor 106 during operation is taken away by the flowing air to dissipate the heat of the driving motor 106. Through the setting of the filter net 206, dust in the air is filtered to prevent excessive dust from entering the interior of the protective shell 201 through the heat dissipation groove 205.
